This spring or bead stopper grips the end of pretty much any thread and stops your beads from falling off. We have used this gadget with all types of thread like stretch magic, beadalon and nymo and it hasn’t affected the thread in anyway (like kinking or weakening the thread at the point where it grips). These bead stoppers are easy to use, just pinch the two wing loops together to expand the spring to enable you to place your thread/threads between the springs. No more messing around with stopper beads or using sticky tape.
These are sold individually.
